This component provides direct access to the console (vga console and
keyboard) to RTLinux-GPL.


Description:
============

Currently, RTLinux human user interface capability is limited to
directly print strings via functions: conprn() or rtl_printf(). Direct
user input from keyboard is not possible. Complex interaction with the
human user (data representation, and user input) has to be done by a
non real-time Linux application communicated with the RTLinux
application via shared memory or RT-FIFO's. These communication
mechanisms are non-portable specific RTLinux facilities. 

Also, the access to the video and keyboard can not be done in
real-time since it is delayed until Linux became active. RT-Terminal
is a new component that allows to RTLinux applications display data
directly on the console screen and read the pressed keys directly from
the keyboard. RT-Terminal will provide direct access to the console to
RTLinux applications and at the same time it will keep compatibility
with the existing Linux console drivers. RT-Terminal will also be used
by the Stand-Alone RTLinux component, since standalone can not use the
linux kernel to print on the screen.

Installation:
=============

First you need a clean copy of the RTLinux-GPL source code:

1.- Apply the patch in patches/rtlinux-3.2-pre1_rtlterminal_1.0.patch
 	$ cd $(RTLINUX)/
	$ patch -p1 < patches/rtlinux-3.2-pre1_rtlterminal_1.0.patch
2.- Go to $(RTLINUX)/drivers/rtlterminal and type make
3.- Insert the rtlterminal module "insmod rt_terminal.o"
	At this point, when pressing F10 key nothing happens unless
	you use the rt_terminal example or create your own code

Examples:
=========
1.- Go to $(RTLINUX)/examples/rtlterminal
2.- Type make
3.- insmod ../../drivers/rtlterminal/rt_terminal.o
    insmod screen_print.o 
    and press F10 key
